Arsenal and West Ham United served up a drab affair during Tuesday's 2017 Carabao Cup action, but a single goal from Danny Welbeck won the Gunners a spot in the semi-finals.
The striker scored shortly before half-time, and West Ham never came close to an equaliser in the 1-0 Arsenal win.
Here's a look at the team sheet, via James Olley of theLondon Evening Standard:
Arsenal's rotated squad took control early, and Welbeck threatened with a weak header after a good cross from Mathieu Debuchy.
The Gunners were comfortable in possession, but it became clear early their fringe players and backups were lacking a rhythm, and their passing was sloppy.
